The Internet exchanges (INXes) provide the only neutral facility for ISPs and operators of Internet Protocol (IP) networks to connect and exchange traffic in South Africa. The exchanges encourage the routing of domestic Internet traffic by providing an optimal path for traffic to reach other networks within the same city, country or continent. This reduces the usage of expensive long-distance links and improves network performance.

Connecting to any of the INXes is easy, and open to any network that has its own IP address space and an autonomous system number.
